It’s difficult to tell what the gravity on another world is for sure without going there, as density can vary between worlds, but it doesn’t take much to begin adding the pounds. The astronomers used a gravitational microlensing technique to spot the planet. And since your planet is very large it's uncompressed density must be much lower than Earth … The super-Earth Kepler 62f, estimated to be around 40% larger than Earth. To find the super-Earth, Martin and the other researchers used a gravitational microlensing technique. If a planet had eight Earth masses and 2.83 times the radius, its surface gravity would be exactly 1g. Since mass grows by the cube and gravity falls by the square your planet would have 1000 Earth masses and surface gravity of 10g, assuming they have same density. But if there is life on them, gravity might be trapping them there. Hippke calculated that the size of the rockets needed to blast through the thick atmosphere of Super-Earths need to be 70% wider than Earth and around 10 times larger! Astronomers call them super-Earths. The super-Earth discovery was a fortuitous event that UC described as "one in a million." Twice as big in volume as the Earth, HD 40307g straddles the line between "Super-Earth" and "mini-Neptune" and scientists aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. Of those 53 planets that astronomers have deemed potentially habitable, about 30 are known as “super-Earths." Experience the Gravity of a Super Earth. But it’s amazingly easy to imagine a super-Earth with a comfortable gravity. It … It orbits very close to its star, whipping around it every 18 hours. According to the study, the super-Earth's host star is about 10% the mass of our sun, and the planet would have a mass somewhere between that of Earth and Neptune. right down. Because of the planet's proximity to the star, it is tidally locked by gravity just as our Moon is to Earth. Astronomers are discovering they may be one of the most common planets in our galaxy. A super-Earth is a planet that's similar to Earth, but larger. The toasty super-Earth 55 Cancri e is relatively close to Earth at 41 light-years away. uploaded by Jelly. The strong gravitational pull of Super-Earths would exert great drag any rocket powered spacecraft that woudl attempt to leave the the surface. Super-Earth Spacecraft. Volume increases as a cube and surface area as a square, so even a slightly bigger planet would have much stronger gravity.
